Question

A block of wood weighing 18 pounds rests on an inclined plane that makes an angle of 60° with the horizontal. To the nearest pound, how much friction force is needed to prevent the block from sliding on the plane?

Answer 1

for this use this formula F = W*sin(angle)

Answer 2

So like F=18sin60?

Answer 3

yes
